In The Crystal Palace, the story of the beautifully vibrant female preacher continues as she carries on the work of the "Little Church in the Valley" to a much larger audience. In addition to the immense numbers of new congregants that fill the Crystal Palace every time the doors are open, the young minister is developing a nationwide television market. Simultaneously, Devin Bannock, the power behind the "miracle in the valley", has gone on the road with his dad, the Reverend Dale Bannock, to work the revival circuit. Despite his tender years, Little Devin has built a nationwide following in his own right, and routinely preaches to sold out venues. The most conspicuous recipient of Devin's gift, Bubba Hawker, has returned to minister the church his grandfather started over 100 years ago. In a bit of karmic serendipity, Bubba lands a record deal for a gospel album that shoots right to the top of the charts. The former "lost soul" now commands riches and fame beyond his wildest dreams.

The church elders are challenged to keep all of the elements of their evangelical machine: the theme park, the revival ministry, and the television network, fine-tuned and running smoothly. Eventually, the elders' personal lives come into the public eye, threatening to leave the entire operation in ruins.
